Merge branch 'jc/all-negative-pathspec'

A git subcommand like "git add -p" spawns a separate git process
while relaying its command line arguments.  A pathspec with only
negative elements was mistakenly passed with an empty string, which
has been corrected.

* jc/all-negative-pathspec:
  pathspec: correct an empty string used as a pathspec element

# Depending on the command, all negative pathspec needs to subtract

# The sample tree checked out at this point has:
# file
# sub/file
# sub/file2
# sub/sub/file
# sub/sub/sub/file
# sub2/file

# but there may also be some cruft that interferes with "git clean"
